Study Design – A prospective cohort study enrolled neonates with low cord pH (n=18), moderate-severe HIE (n=40), and healthy controls (n=38). Groups provided serum samples at 0-6 h of life. The concentrations of biomarkers and miRNAs were compared between cohorts. Result – The low cord pH and moderate-severe HIE groups had increased concentrations of GFAP, NFL and Tau compared to controls (P<0.05, P<0.001 respectively). NFL concentrations in mild HIE was higher than controls (P<0.05) but less than moderate-severe HIE (P<0.001). Of 68 miRNAs, 36 in low cord pH group and 40 in moderate-severe HIE were upregulated compared to controls (P<0.05). Five miRNAs in low cord pH group(P<0.05) and 3 in moderate-severe HIE were downregulated compared to controls (P<0.05). Conclusion – A biomarker panel in neonates with low cord pH may help clinicians make real-time decisions.
